FORM FOR MAKlNG INDIA-RUBBER BOOTS AND SHOES.

SPECIFICATION forming part of Letters Patent No. 258,513, dated May 23, 1882.

Application filed April '24, 1882. (No model.)

' drawings constitute part of this specification,

and represent, in-

Figure 1, a vertical section of the form for shoes; Fig. 2, a sectional side view of the form for boots; Fig.3, a rear View of the upper part of the form and suspending-rod; Fig. 4, a per.- spective View of the pin employed for suspending the form on the rack.

This invention relates to an improvement in forms for making india-rubber boots and shoes. These forms have usuallybeen made from wood, solid, and no matter how well the wood may be seasoned the great heat to which they are necessarily exposed in vulcanizing the boot or shoe soon cracks the forms, necessitating repair or rendering them useless. Again, the forms thus made of wood are very heavy and clumsy for the workman to handle.

The object of my invention is to construct these forms so as to withstand the heat and use without injury, and make them very much lighter than the forms heretofore constructed;

and it consists principally in a form for boots or shoes made hollow from papier-mach, and as more fully hereinafter described.

The general outline of the form, it will be understood, is the same as the forms heretofore constructed, depending only upon the shape of the boot or shoe required to be produced, and the form for the boots is made in parts-that is to say, the leg detachable from the foot portion-so that the leg form may be first removed from the boot, then the foot portion.

The form is made in molds prepared of the shape corresponding to the exterior of the shape of the form required, and in these molds the papier-mach is placed while in a plastic condition, forming a thin shell, only so thick as will be sufficient to stand the wear and tear of the work to be done upon them. The forms thus molded are cured in the usual manner of curing papier-mache, so that when completed they present a smooth hard surface, very light as compared with wood, and capable of withstanding the heat of vulcanization without in jury or effect.

In Fig. 1, A represents the form for overshoes in longitudinal section. In Fig. 2, B represents the foot or toe portion of the bootform, and C the leg, niade separate one from the other, and the two secured together, it may be, in the usual manner; but I prefer a rod, a, which is introduced through the upper end of the leg-form and passes down through it into a corresponding hole, I), in the foot portion, and through a metal socket, C, introduced into the foot portion of the form in the process of manufacture. The lower end of the rod has a cross-piece, (1, making it T shape, and the opening through the socket and form is such as to permit the cross-piece cl to pass down through, and then, when below the socket, to be turned across the opening, as seen in Fig. 2. At the upper end a cam-lever, e, is hung in the rod, which, when the rod is engaged with the foot-piece below and the cam is turned down and made to bear upon a seat-,f, on the top of the leg-form, clamps the two parts together. They are released by turning the lever up, as indicated in broken lines, Fig. 2. Then the rod may be turned so as to withdraw it from the socket below to permit the leg to be first withdrawn, and then the foot from the boot, which has been made thereon. The upper end of the rod is constructed to form a loop, D, by which it may be hung in the oven.

Instead ofusing the clamp and the T-shaped end of the rod, as described, the socketC may beafixed nut, and the rod screwed thereto so as to he turned into the nut, with a collar on the rod above it to clamp the two parts together, which is a common and well-known construction; but I prefer the clamp because it facilitates the work of attaching and detaching the forms.

To insure the proper position of the rod, so that the loop shall stand transversely across the leg, as seen in Figs. 1 and 3, I make a recess, h, on the top of the form, into which the arm 2' of the lever will stand when turned down into its clamped position, thus serving as a latch or look to hold the rod.

In hanging the forms on the rack a difficulty is experienced from the fact that the forms will turn on their suspending books or pins to the right or left and come in contact with the next adjacent boot, such contact defacing the surface and injuring the appearance of the boot, which must be sold as a defective boot or lost. To obviate this difficulty and prevent the boots coming in contact when once hung upon their book, either by turning or swinging, I construct the loop with shoulders m upon the inside and opposite each other; and I construct pins E, as seen in Fig. 4, shaped in transverse section corresponding to the shape of that portion of the loop above the shoulders m, and these pins are driven into racks, and then when required to hang the forms the boot is passed onto the pins, as seen in broken lines, Fig. 2, and also seen in section, Fig. 3. The under side of the pin fits upon these shoulders, which prevents the forms swinging in either direction, and also prevents the form from turning upon the loop to the right or left, so as to bring the foot of one form into contact with the foot of the next.

I claim- 1. As an article of manufacture, a form for making indiarubber boots or shoes, constructed from papier-maeh and made hollow, sub stantially as described.

2. A bootform for making india rubber boots, consisting of the leg and foot sections, the foot-section, provided with the socket 0,

and the rod on, constructed with the T-shaped end, to pass through the socket in the foot, the rod extending up through the leg to form the loop, combined with a cam-lever hung to the said rod, whereby the leg is clamped to the foot portion or detached therefrom, substantially as described.

3. A boot-form for making india-rubber boots, consisting of the leg and foot sections, the foot-section provided with the socket G, the rod a, constructed with the T-shaped end, to pass through the socket in the boot, the rod extending up through the leg to form the loop, combined with a cam-lever hung to the said rod, whereby the leg is clamped to the foot portion or detached therefrom, and the top of the form constructed with a recess, h, in which the arm will lie when the parts are clamped together, substantially as and for the purpose described.

4. A rod for clamping the leg to the foot portion of a boot-form for making india-rubber boots, provided with a loop at its upper end, constructed with shoulders m m, that part of the loop above the shoulder corresponding in shape to the transverse section of the pin upon which the form is to be suspended, substantially as described,
